Application filed June 22, 1911. Serial No. 634,?60.

To all whom 1' I may concern:

Be it known that LALEXANDER M. NEEPER, residing in the city of Pittsburgh, county of Allegheny. and State of Pennsylvania, have invented new and useful Improvements in Car-Truck Side Frames, of which the following is a specification.

My invention relates to forg ed o r pressed car truck side frames and the objects of my improvements are to provide a car truck side frame made from a metallic bar of rectangular cross section in which the parts thereof performing the functions usually'performed by the several arched bars and tie bars of frames made from arched bars and tie bars bolted together, are integral with each other, and adjustablemeans afiixed to my improved car truck side frame for receiving and re taining the bolster of the car and the journal boxes of the wheels thereof.

My invention consists in a slitted bar of rectangular cross section; a car truck side frame made from said bar, preferably by pressing or forging; and adjustable means aiiixed to said car truck side frame for affixing the bolster of the car and the journal boxes of the wheels of said car to said frame.

In theaccompanying drawings which illustrate my intention Figure. 1 shows the side elevation of my improved slitted and slot-ted bar X, of rectangular cross section. Fig. 2 is an enlarged end view of my improved bar X. Fig. 3 is a side elevation of my car truck side frame made from said bar X with the adjustable means of aitixing the bolster and the journal boxes thereto shown, thereon. lnll ig. l B is a brace shown in side. elevation; A is a sleeve adapted tobe placed over bolt C when said bolt is placed through the bolt holes in brace 13.

Similar reference characters refer to like parts throughout the several figures.

In Fig. 1, X is a bar of metal, preferably of steel of rectangular cross section: a slot 3-3 is made parallel to its upper surface and located about an equal distance on each side/of its medial line, the slot terminating some distance from each end of the bar. 44. 4'4 are two slits extending from the respective ends of the bar toward the medial lino passing terminal points of slot 3-3, The planes of the slot and the slits are parallel to the planes of the upper and lower surfaces of the hair. in the bar. 1 represents that portion of the bar wh ch is above the slot 3 3. 2 represents that poi tion of the bar between the end of the slot at 3 and the left hand of the bar as shown in the drawing, which is-above slit 4-4. 2' represents that part of the bar which is between the right hand end of the bar as shown in the drawing and the end of the slot at 3 and above the slit 4'4'. 5 represents that part of the bar which is between the left hand of the slot and the right han-ci end of the slit 44. 5 represents that portion of the bar which is between the end of the'slot at 3 and the end of the slit 4-4. 6 represents that portion of the bar which is below the slot 33 and between the ends of the slits and the lower surface of the bar. 7 represents that portion of. the bar which is below slit 4 and between said slit and the bottom surface of the bar. '7 represents that portion of the bar which is below slit 4-l and between said slit and the lower surface of the bar. These reference figures as thus described appear in the car truck side frame when the same is expanded as shown in Fig; 3 and show the relative positions and relations of the several parts of bar X when the same has been expanded to form the frame of my improved car truck side frame.

In making up the bar X a bar of rectangular cross section of suitable size is taken and the slot 3-3 is made therein by drilling or sawing or any suitable method substantially in the position and of the size as shown inFig. 1. The slits H, 4.-'4' are made from the IGSPECtlYQ ends of the bar by sawing or drilling or other suitable method and in substantially the position and the dimensions shown in Fig. 1. When the bar has thus been slitted and slotted it is heated and bysuitable press with suitable forming dies is pressed into the shape shown in Fig. 3. The various portions of thebars 1.2. 2. 5. 5". ti. 7. 7', taking the posiv lions and having the relations with reference to each other shown in Fig. 3.

ing: flanges 8". which are longer at end than at end 11. Said channels are placed upon the car truck side frame so that the lhnwos thereof shall extend toward the ends of t w nlllt frame and inclose nix-ts 1. 1, 5, and a of said frame and so hot the webs slol' opening ll in Fig. :l. Said flanges hav- In Figs. 3 and 4. 8-8 are channels havthereof shall form two of tin sides of bolj centric.

ing holes 8, 8", located asshown in Fig. 3, and so that bolts 11 of Fig. e'may pass through said holes, which are opposite to each other in said flanges 8. Cylindricalsleeves 10 are placed opposite saidholesin said flanges, so that the holes in the flanges and the holes in said sleeves shall be con- The bolts 11 are then passed" through the holes in the flanges and the holes in said sleeves, and nuts 11" are afixed to said bolts 11. The sleeves 10 are of such diameter, that when bolts 11 are passed through them as aforesaid, the peripheries of said sleeves contact with the opposite sidesvof the members 1, l, 5, 5, of the frame shown in Fig. 3 and forming the sides of opening 12. Said sleeves thus bolted on the opposite sides of said members hold said 0 annels 8 in position upon the car truck side frame. The positions of said channels 8 on said car truck side frame may be varied by varying the diameter of said sleeves 10, and because thereof, said channels are adjustable on said car truck side frames; In Fig. 3, the-opening between member 1 at the top of said figure and the inside edges of channels 8, 8 and part 6 of the frame, form an opening for the placing of the bolster of the car IIDOIL WhlCh said' car truck side frame may e used. The parallelogram having the small circle 9 at each end of the truck side frame between 2-7 and 2'-7' respectively, represent journal boxes which are held in place between said last. mentioned bars and the frame by bolts 9, 9, 9, 9. The journal boxes may be of any suitable construction, as may said bolts 9,

9, 9, 9, which extend through 7 to 2 and through 7' to 2 respectively.

While the bar X is shown in Fig. l with the two end slits, these slits may be omitted and the bar formed with the slot 3-3 alone, the lower surface being then defined by the lines on the upper side of the slits 4-4 and 4:- l and a straight line connecting the inner ends of said lines with said slits. In this case, the tie bar formed by the parts of bar X, 7, 7 and the lower part of '6, would not be attached to the framecomposed of the bar which would be slotted only and from which the end slits, would be omitted. A bar having only the slots could be ex )andedthe same as the slitted and slotted liar and a car truck side frame would result which would be represented by those parts of the car truck side frame shown in Fig. 3 which are designated by, 2, 2, 1, l, l, 5, 5, and the upper half of 6. Such a car truck side frame would eliminate many of the bolts and devices which are at resents" from those shown and described in the drawing and this specification; instead of channels, plates and distance pieces may be bolted together and used with like effect,

so far as'bracingand adjustability are con-' cerned and so far as aflt'ordinga means of adjustment and affixing a bolster to the car truck side frame may be considered. The same is true of the diagrammatic journal boxes and bolts shown in Fig. 3. Those shown are for the purpose of showing the adaptability of the truck side frame to receive and retain journal boxes of any suitable construction when accompanied by suitable devices for performing functions substantially like the functions performed by the bolts 9.

What I claim as my invention is:

1. A car truck side frame made from a metal bar having a slot and two end slits,

'who'se planes are parallel to the plane of said slot; said slot being expanded so that the parts of said bar forming the sides thereof will form an opening for the reception of a bolster, and the parts of said bar forming the sides of said slits being formed to provide openings for the reception of journal boxes.

2. A car truck side frame made from a metal bar having a slot and two end slits, whose planes are parallel to the plane of said slot, the sides of said slotbeing. expanded and stretched so as to form an opening for the reception of a bolster, and the parts of said bar forming the sides of said slits being formed to provide openings for the receptlon of journal boxes and adjustable means mounted on said frame for affixing a bolster to said frame.

3. A. car truck side frame made from a metal bar having a slot and two end slits, whose planes are parallel to the plane of said slot, the sides of said slot being expanded and stretched so as to form anopening for the reception of a bolster, and the parts of said bar forming the sides of saidv nesses.
